Most pastes are self priming so its not needed.
Also, the sbr layer will make it harder for the paste to dry out.

I know what you're saying I know of some pastes that are self priming ardex d20 I think it is springs to mind but really are you telling me that as you put a paste on the wall it instantly seals the wall to stop any moisture in the paste prematurely drying into the background .

Adhesive powder or ready mix needs to cure not dry to optimise adhesion.

Ready mixed (dispersion) adhesive relies on drying to set, not a chemical reaction like cement adhesive

I'm not suggesting that the pastes seal a porus substrate,rather that they don't necessarily need it sealed.
Pastes are fairly slow to dry and a porus substrate to help aid the process would seem to me, to be a good thing.

Some firey debates on here tonight

Correctly diluted the primer won't prevent adhesive setting
